The project work is anticipated to be done in late summerlearly fall of 2008 and �� will take approximately ten weeks to complete. The arena is considered a year �:� around facility that our affiliated groups and citizens rely on; however, this i� appears to be the best time of the year to do these projects because the arena is 1� typically shutdown each year for a 2-3 week period in August for annual 1�� maintenance. This project will require a shutdown extension of approximately 1�' another 6-7 weeks. As a result there will be significant program impacts that will 1 k need to be worked through. Staffwill be working with user groups and Ramsey 1{r County rinks to attempt to coordinate ice time for them. The opportunity � v cpstlre�enue loss is estimated to be approximately $60,000 for the extended �_ shutdown period and has been planned for in the 2008 proposed budget. { L, �� :. � r] 25 2� � ' �k � �f J� L � :� 1� .� �� �� -f L� 1 ��; �� �� _}1 L � �j ��: �1 1 �� L With this project some unforeseen circumstances may arise, i.e. high frost levels, steel unavailability, chiller barrel corrosion greater than anticipated, more time to make the initial sheet of ice, test well results, etc. If this occurs, the City will be responsible for the additional costs associated with removing the frost and all the testing that is associated with the sub grade preparation, change of direction with steel issues, and new vs. refurbish chiller barrel, etc.. POLICY OBJECTIVE The proposed project and the use of professional engineers are consistent with City �oliG}�pr�c�ti�� for repairslrer�ovatians/cans�ruciion that is necessary for the City infrastructure. The proposed project considers and compares the use of green technology vs. conventional uses. The proposed project considers and compares the financial implications of today as well as in the future.
